The platform 1'7 at its rear edge has secured thereto rods 26, the freeends of which are formed to engage selected apertures 2'7 arranged in vertical series onthe lower portions of the standards 3. One of the rods 22 is provided adjacent its upper end with a keeper plate 28 with which is engageable a lug 29 provided on the handle 14 for retaining the handle 14 projected against the action of spring.16' during the filling of the valve bag 30; 1'

Each of the bars 20 adjacent its lower-portion justable weights 33. The weights 33. can be adjusted as desired for retaining the'platform' I7 normally in a horizontal position. Also, by ade,

justing the bars 18 relative to the bars 20 platform 1'7 may be raised or lowered withrespectto the nozzle '7. l

. Referring again t'o'the'nozzle '7 it will'be'seen that'the'same adjacent its outlet endhas'integral therewith an air passage 34 that terminates at the small end of then'ozzle. The passage 34 has an end 35 suitably'connected with one end of a fiexible conduit tube 36 which is also connected to a dust bag 37. Adjacent theend 35 thereof passage 34 has extending therefrom a nipple 38 to which is coupled one end of a flexible air tube39 that in turn is connected to the outlet port '40 of the casing of valve 12. As will be noted, a second port 41 of the valve is connected to the pipe 10, while the third port 42 of the valve is connected with the coupling 8 for establishing communication between the air pipe 10 and the nozzle 9.

The operation of the device is thought apparent from the foregoing, however it may be briefly explained as follows:

After all adjustments have been made the valve bag 30 has its valve equipped and suitably engaged with the nozzle 7, while the material to be fed to the bag is placed within the hopper 4.

The handle 14 is then pulled against the action core thereof in the position shown in Figure 7 to establish communication between the air pipe 10 and the'nozzle 9; Thus it will be seen that air under pressure will pass through the valve to discharge through the perforations at the end of the nozzle 9 for creating a suction at the outlet 5 of the hopper.

The suction thus created draws the material from'the hopper through the outlet 5, and the material under pressure is forced through the nozzle 7 into the bag 30.

When the bag 30 becomes filled the weight thereof on the platform-17 will cause the'platform 17 and associated parts 'tomove downwardly thus moving the plate'28' out of the path of the lugs 29 and permitting the handle 14 to move and nozzle 7 will ofcourse permit angular move- On the free ends of the levers 31 are ad-.o

ment of the nozzle 7 relative to the outlet 5 upon the downward movement of platform 7 and its associated parts.

It will also be apparent, that during the filling of the bag 30, dust resulting therefrom will be drawn through the passage 34 and the tube 36 into the dust collecting bag 37. Also, when the valve 12 is operated in the manner just explained for directing air through the. hose or tube 29, such air passing through the passage 34 will create a suction at the outlet end of the nozzle suifie cient for removing any accumulations that might otherwise tend to clog up the discharge end of 1 the nozzle 7.

then" made and the next bag is placed on the platform 17 Withthe valve end thereof properly engaged with the nozzle 7. In this connection it will be noted after the filled bag has been removed from the platform 17, the same will move upwardly to its normal position under influence. of the weights 33 on the levers 31. f i Having thus described my invention, wha't'I claim as new is:. 1. In a bag filling device, asupporting structure, a hopper mounted on saidfsup'porting struc-' ture and provided with an outlet, a nozzle, a fiex ible connection between said nozzle and said out-' let, valve controlled means for forcing air through said outlet and said nozzle including an air 'j'et arranged within said hopper in operative position to saidoutlet, and a valve connected with said jet, an operating rod'pivotally connected with said valve, spring means -engagingisaid rod normally urging the same to move in one direction, guide means for the rod mounted on the supporting structure, a bag supporting platform, means for suspending said platform in a manner for vertical movement, and including weight means for normally retaining the platform in an elevated position, a lug on said valve actuating member, and a member arranged in the path of the lug and movable with the platform for releasing the valve actuating member upon downward movement of said platform. 2. In a device of the character described, a hopper provided with an outlet, a nozzle connected with said outlet, an air tube integral with said nozzle and terminating at' one end at the discharge end of the nozzle, an air nozzle ar ranged in said hopper in operative position to said outlet, an air conduit connected with said nozzle, a three way valve in said conduit, a fiexi-' ble tube connecting one end of the airtube associated with the nozzle with one side of said valve,-and means for operatingsaid valve for directing the air selectively to the air nozzle or to the aforementioned airtube associated with the first named nozzle. 1

3. In a device of the character described, a hopper provided with an outlet, a'nozzle connected with said outlet an airtube integral with said nozzle and terminating at oneend at the discharge end of the nozzle, an air nozzle arranged in said hopper in operative position tosaid outlet, an'air conduit connected with said nozzle, a three way valve in said conduit, a flexible tube. connect-.

ingone. endofthe air tube associated with the nozzle with one side of said valve, and means-for operating'saidvalve for directing the airselec tively to the air nozzle-pr to the aforementioned air tube associated with the first named nozzle, a dust bag, and a hose connection between "said dust bag and the aforementioned air tube.

LOO

combination, a hopper, a nozzle for said hopper provided externally with an air tube, said tube extending substantially longitudinally of the nozzle and terminating at one end adjacent the discharge end of the nozzle, a conduit tube connected with the said air tube intermediate the ends of the latter, and air blast means connected with the air tube at the end of the tube remote from the discharge end of the nozzle.
